Hello, and sorry if this post is seen as a nuisance question, but I started my Half-Life modding journey fairly recently, I have a good basis and general knowledge of VS studio and the .dll compiling and such, but I cannot for the life of me figure out where effect / debris / gun casing effect parameters are stored, such as lifespan, and physics, as I can find some of it in the .cpp files and others, but I cant seem to find lifespan and world related code, and any changes I make to what I *think* could be it, dont work. I want to add the slight detail of casings leaving a more longer trail to make firefights more detailful, and maybe more smaller additions as I develop the mod. I have attached several images in hope that my unmatured brain just skipped over or couldn't understand where these were located. I will admit I do need help on what files to keep and delete, as I dont know much between hl_cdll and hldll other than cdll probably is client, nor do I know what the dmc files are for nor do I know what ricochet is, I assume they're for other valve titles / quake as dmc mentions it. Again, sorry if this post is bothersome to most, as I dont know where most of the community resources / help is. Small questions about what the mod is / tips for me would be greatly appreciated!
